Cookie Policy
Last updated October 7, 2026
This policy explains the cookies and similar browser storage Launch Commons (launchcommons.com) uses, what each one is for, and how you can control them.
2. What we use
We keep this short on purpose. Launch Commons has no advertising cookies, no ad trackers, and no cross-site tracking, and we don't sell anything we learn from cookies.
Strictly necessary
The site can't work properly without these, so they don't need your consent.
| Name | Type | What it's for | How long |
|---|---|---|---|
| __Host-lc_session | CookieLaunch Commons | Keeps you signed in after you log in. It holds a random value, not your password, and the site's own scripts can't read it. | Until you log out, or after 30 days without visiting the site |
| auth_session | Local storageLaunch Commons | Remembers your name and when your sign-in ends, so the top bar shows them straight away. | Until you log out |
| lc_after_oauth | Session storageLaunch Commons | Remembers which page to send you back to after you sign in with Google or GitHub. | Removed as soon as you're signed in, or when you close the tab |
Preferences
These remember choices you make so you don't have to make them again.
| Name | Type | What it's for | How long |
|---|---|---|---|
| sidebar-collapsed | Local storageLaunch Commons | Remembers whether you collapsed the sidebar. | Until you clear your browser data |
Video performance
Set by our video player when you watch a video. They help creators see how their videos do and help us fix playback problems.
| Name | Type | What it's for | How long |
|---|---|---|---|
| muxData | CookieMux, our video provider | A random ID for your browser and your viewing session, so views and watch time are counted once rather than on every page load. It doesn't contain your name or account. | Up to a year, or until you clear your cookies |
3. Google and GitHub sign-in
If you choose “Continue with Google” or “Continue with GitHub”, you sign in on their website, and they may set their own cookies there under their own cookie policies. Launch Commons doesn't receive or read those cookies.
4. Your choices
- Log out to remove the sign-in items straight away.
- Clear your browser's cookies and site data to remove everything on this page. Every browser has this in its privacy settings.
- Block cookies in your browser settings. You can still browse and watch videos, but you can't stay signed in to Launch Commons without its sign-in cookie.
- Global Privacy Control and Do Not Track: we don't use cookies for advertising or to track you across other sites, so there is nothing extra for these signals to switch off.
You can learn more about managing cookies at allaboutcookies.org.
5. Changes to this policy
If we start using a new cookie, we'll add it to this page and update the date at the top. If we ever want to use cookies for anything beyond what's listed here, such as analytics or advertising, we'll ask for your consent first.
